Contrast of tone.

Formed by the juxtaposition of light and dark values. This could be monochromatic (single colour). If you remove the chromatic value the tonal value can be defined more easily.

COLOUR EXPERIMENTS

Yellor and green have a medium contrast as they are close to each other on Ittens colour wheel.

Blue and green have a low contrast as they are close to each other on Ittens colour wheel.

Blue and orange have a stronger contrast as they are further apart on the colour wheel and blue has a darker tonal value.

Red and orange have a strong contrast of tone as red has a stronger tonal value than orange, this is clear when we look at the monochrome photo.

Blue and yellow have a stong contrast as they have as blue has a stronger tonal value than yellow.

Yellow and magenta have a strong contrast as violet has a much darker tonal value than yellow, this is apparent in the monochrome photo.

Blue and Violet form a low contrast as they have similar tonal values.

Orange and blue have a strong contrast of tone, but when we place the coloured circles on a yellow background the contrast becomes less intense.

Blue and green have a low contrast, this is not affected when placed on a coloured background.

Orange and yellow create a low contrast of tone.

Finally, I experimented with placing three colours together to see if it affected the contrast of tone. The colours red and green clearly have a similar contrast of tone as they are both quite dark. The orange contrasts these as it has a lighter tonal value.

Contrast of hue.

Formed by the juxtaposing of different hues. The greater the distance between hues on a colour wheel, the greater the contrast. Therefore, complimentary colours have the greatest contrast of hue.

COLOUR EXPERIMENTS

Green and blue have a medium contrast.

Blue and orange have a strong contrast as they are complementary colours.

Red and yellow also have a low contrast as they are both primary colours.

Red and blue also have a medium contrast.

Moreover, yellow and orange also have a medium contrast as they are next to each other on the colour wheel.

Yellow and green have a low contrast.

Blue and yellow have a low contrast.

Violet and magenta have a low contrast of hue as they are close to each other on the colour wheel, colours that are close to each other have a lower contrast.

Therefore blue and violet also have a low contrast.

Orange and green have quite a strong contrast as they are almost opposite on the colour wheel.

Red and violet have a medium contrast.

Contrast of saturation.

Formed by the juxtaposition of light and dark values and their relative saturations.

Contrast of temperature.

A selection of warm colours on a grey background. Shooting these images with artificial light has affected the colours making them seem a lot darker that they are when viewed in sunlight.

Cold colours on a grey background.

Orange on yellow, these colours are both classed as warm colour so don't create much of a contrast.

On the other hand, this violet cd is classed as a cold colour and creates a strong contrast with the yellow background.

The orange and red circles are both warm colours and contrast the blue background.

Below I arranged a number of warm colored circles on a yellow background, there is no contrast caused by the colours.

Little contrast is caused between the yellow and green circles as they have a similar chromatic value.

A strong contrast of temperature is created by the violet cd and the red circle.

Finally, I experimented with trying to balance the colours by making an even arrangement of warm and cold colours. However this did not work, I would need to use the contrast of extension to help me balance warm and cold colours.

Complimentary contrast.

Formed by juxtaposing complementary colours from a colour wheel or perceptual opposites.

Complimentary colours such as red and green, or blue and orange have the harshest complimentary contrast as they are directly opposite each other on the Itten's colour wheel.
